Supplementary Figure 1: Probabilities for each treatment can be plotted in absolute rankograms or cumulative rankograms. A simple numerical summary supplying the graphical display of cumulative ranking used to estimate the surface under the cumulative line for each treatment. Larger SUCRA means the drug has lower ranking.

Supplementary Figure 2: The forest plots for inconsistence check showed that most loops’ 95%CIs included 0, meaning the direct estimate of the summary effect was not different from the indirect estimate.
